3D model description

3D printed radio-controlled model of a mini excavator in 1/8.5 scale.

To print this model, you need about 2.5kg of filament of different colors and types. All parts can be printed on printers with a print area of 180x180mm, except for tracks. They must be printed on a printer with a print area of at least 210x210mm. Most parts can be printed with any type of filament, such as PLA, ABS, PETG, but tracks must be printed with flexible filament! Therefore, your printer must be able to print with flexible filaments! More information about filament types can be found in the printable parts list: link

All the necessary information for building the model, such as a list of non-printed parts for purchase, a list of fasteners, some characteristics and features of the model, you can find in the assembly instructions for this model: link

In the archive with the model, you can find individual parts as well as parts combined into small groups, which will help you simplify the process of preparing parts for printing. Some print groups are too big for 180x180mm printers, so if you have a printer like that, you need to print these parts from individual parts folder! Some individual parts are too large for 180x180mm printers, so you will need to print these parts from the Alternative Parts folder.
The archive also contains some alternative versions of parts for printers with 300x300mm print area. Some parts are combined, which will simplify the process of assembling the model!

All parts for the model are designed to be printed with minimal using or not using material. Check out the printable parts list at the link above!

Right now I don't have good photos of this model, so I'm only attaching renderings. You can see some real photos and videos

The main characteristics of the model:
- RC model, 1 : 8.5 scale
- Realistic exterior look and Detailed interior
- Openable Cab door, side gate, hood
- Fully functional model
- Electric linear actuators used
- Tracks from flex filament
- 116 printing parts
- 24 printing groups
- 2.5 kg filament
- Can be printed with 180x180mm printers
- Length with arm - 682mm
- Width - 235mm
- Height - 297mm
For more sizing information, see the assembly instructions at the link above!

Update 22 April 2025
- Cabin interior is divided into smaller parts, for printing them in different colors, for better detail.
- Added covers for chassis motors to prevent dirt from getting into them.
- Added holder for ESCs
- Revision of holes for installing bearings
- Multiple small optimizations of parts for printing.
- Revision of the slew bearing
- Changed the sizes of holes for wiring
- Added more recommendations to the assembly instructions

Update 25 April 2025
- Added a tool changing mechanism

Update 02 May 2025
- Reworked drive sprocket
- Added bracket for sprocket s
This will reduce the risk of losing the track belt while driving in sand.
